Attributes for NHDPlus Version 2.1 Catchments and Modified Routing of Upstream Watersheds for the Conterminous United States: Mean Rate of Phosphorous Application on Agricultural Land from Census of Agriculture, 1997

Metadata Updated: October 28, 2023

This tabular data set represents the mean rate of phosphorous from fertilizer and manure applied on agricultural land in 1997 compiled for two spatial components of the NHDPlus version 2 data suite (NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID. The source data for mean rate of nitrogen from fertilizer and manure applied on agricultural land in 1997 was produced by Ruddy and others, (USGS, 2006). Units are kilogram per square kilometer. Reach catchment information characterizes data at the local scale. Reach catchments accumulated upstream through the river network characterizes cumulative upstream conditions. Network-accumulated values are computed using two methods, 1) divergence-routed and 2) total cumulative drainage area. Both approaches use a modified routing database to navigate the NHDPlus reach network to aggregate (accumulate) the metrics derived from the reach catchment scale. (Schwarz and Wieczorek, 2018).
